<p>In machines for the coupling of films with solvent-free adhesives, a spreading station (1), which comprises a pair of batching rollers (3), a spreading roller (5) and an intermediate roller (4) arranged in such a way that the plane containing the axis of the intermediate roller (4) and the axis of the batching roller (3a) in contact with the intermediate roller (4), forms an angle alpha comprised between 80 degrees and 100 degrees with the plane containing the axis of the intermediate roller (4) and the axis of the spreading roller (5). Also disclosed are means to vary micrometrically the relative positions of the batching rollers (3) in reciprocal approaching and distancing, comprising a differential screw (10) and a reduction gear (11). <IMAGE></p> |
